Built-in Infrared Port on Laptop or Desktop

A Built-in Infrared (IR) Port on a laptop or desktop is a hardware feature that enables communication between devices using infrared light. It was commonly used in the past for connecting peripheral devices, such as printers, mobile phones, and other laptops, without physical cables. However, with the rise of Bluetooth and Wi-Fi, infrared ports have become less common in modern computers.

When your computer has a built-in IR port, it allows data transfer over short distances (typically up to a few meters), using infrared light signals to transmit data.
